How I Made It: Charlie Bigham's, founder of Bigham's

So when he was 28 he gave up his job, bought a camper van and spent nine months driving overland to India with his girlfriend in the hope of finding inspiration.

He found it while eating food in local markets along the way. He said: “I suddenly realised my business should be about food and preparing the ingredients to be cooked quickly, because that is what everybody does around the world.

“If you go into a market stall in Turkey or Morocco, you sit down in front of them. They toss a few things in a pan, and it’s ready. I realised that convenience doesn’t have to mean putting something in a microwave. It can mean quick, fresh food.”
